CareFusion Micro I Bedienungsanleitung Seite 85

a
Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radio, amateur radio, AM and
FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the model Micro 1 is used
exceeds the applicable RF compliance level above, the model Micro 1 should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orientating or relocating
model Micro I.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m
Recommended separation distances between portable and mobile RF
communications equipment and the Micro I
The Micro I is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Micro I
can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment
(transmitters) and the Micro 1 as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (m) can be estimated using the
equation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in Watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures objects and
people.
